Description

Technical Field

[0001] The present application relates to the technical field of common rail pipe drilling, and more specifically, to a drilling device for a common rail pipe of an engine. Background Art

[0002] High-pressure common rail electronic fuel injection technology refers to a fuel supply method that completely separates the generation of injection pressure and the injection process from each other in a closed-loop system composed of a high-pressure fuel pump, a pressure sensor and an electronic control unit. The high-pressure fuel pump delivers high-pressure fuel to a common fuel supply pipe, and accurately controls the oil pressure in the common fuel supply pipe, so that the pressure of the high-pressure fuel pipe is independent of the engine speed, which can greatly reduce the degree to which the diesel engine's fuel supply pressure changes with the engine speed. In the process of processing and producing the engine common rail pipe, corresponding drilling equipment is needed to perform corresponding drilling operations on the common rail pipe.

[0003] With respect to the above-mentioned related technologies, the current drilling equipment is usually used to perform a single drilling on the common rail pipe. After the drilling is completed, the drilling position is adjusted to perform another drilling.

A normal common rail pipe needs to be drilled in a straight line with equal distances.

When the active boosting assembly 240 drives the drilling part of the common rail tube body to move below the drill bit 140, the active boosting assembly 240 will be connected to the magnetic adjustment assembly 250, thereby disengaging from the counterweight translation plate 220, and then stopping the transmission of the counterweight translation plate 220, and the subsequent limiting assembly 290 locks and fixes the counterweight translation plate 220 The position of the plate 220 is determined, and finally the drill bit 140 is lowered to the height of the common rail tube body to perform the drilling operation.

During the resetting process, the limit assembly 290 will be disengaged from the counterweight translation plate 220 and the movable booster assembly 240 will be connected to the bottom of the counterweight translation plate 220 again. At this time, the movable booster assembly 240 will move at the bottom of the counterweight translation plate 220 and will not transmit its movement. When the displacement assembly 230 is opened again to drive the drill bit 140 to descend, it will drive another punching part of the common rail tube body to move below the drill bit 140, thereby performing continuous drilling. There is no need for frequent operation by the staff to achieve continuous drilling, and the position of the magnetic adjustment assembly 250 is adjustable so that the distance of each displacement can be adjusted according to the drilling spacing requirements of the common rail tube body, thereby improving the applicability of the equipment.

[0037] The displacement assembly 230 includes two mounting plates 233 fixedly connected between the top and bottom of the inner wall of the main frame 110. Both sides of the top of the main frame 110 are provided with movable grooves. The interiors of the two movable grooves are movably connected with linkage plates 231. The tops of the two linkage plates 231 are hinged with two first connecting arms 232.

The limit assembly 290 includes a plurality of locking grooves 292 opened on both sides of the counterweight translation plate 220. The adjacent sides of the linkage plate 231 are fixedly connected to the limited plug rod 291, and the two limited plug rods 291 are adapted to the multiple locking grooves 292. The adjacent ends of the two movable grooves are provided with an adapter hole 293 adapted to the limited plug rod 291. The movable booster assembly 240 includes two T-slots opened on the top of the inner wall of the main frame 110, and the insides of the two T-slots are slidably connected with a movable plate 241, and the movable plate 241 extends to the outside of the two T-slots.

While driving the drill bit 140 to move downward, the two second connection arms 247 will push the movable plate 241 to move. When the movable plate 241 moves, The ratchet bar 242 will be pushed by the ratchet rod 243, and the ratchet bar 242 will drive the counterweight translation plate 220 to move a certain distance inside the translation groove 210. When the counterweight translation plate 220 drives the drilling part of the common rail tube body to move below the drill bit 140, the metal block 244 will be pulled down by the suction force of the magnetic block 255 so that the ball 245 contacts the magnetic block 255, so that the ratchet rod 243 is separated from the ratchet bar 242, and the transmission of the counterweight translation plate 220 is stopped.

When the adjustment block 254 moves, it will drive the magnetic block 255 to move, so that the position of the magnetic block 255 is adjustable.

The rotating steering wheel 253 drives the one-way screw rod 252 to rotate, and the one-way screw rod 252 will drive the adjustment block 254 to move. When the adjustment block 254 moves, it will drive the magnetic block 255 to move its position, so that the position of the magnetic block 255 is adjustable. The position of the subsequent adsorption metal block 244 changes, and then the distance of each displacement can be adjusted according to the drilling spacing requirements of the common rail tube body, thereby improving the applicability of the equipment.At the same time, the position of the numerical slot 257 indicated by the pointer 256 can be used to know the displacement distance of the common rail pipe body each time, so as to facilitate the staff to make adjustments.
